tiffany

This rendering example creates textured objects with Tiffany Blue coloration. It uses bidirectional path tracing to greatly reduce variance (versus standard path tracing). It shows how one might render:

• Inset ceiling lights
• Area lights
• Textures - both hard-coded and image-based

By default, this demo outputs a grainy, low-resolution rendering (which takes a minute or two):

Raising the quality and resolution is as simple as modifying these lines:

NumSamples: 200,
MinSamples: 200,

and this line:

img := render3d.NewImage(200, 200)

Simply increase NumSamples to maybe 100000, increase MinSamples to 1000, and increase the resolution from 200x200 to whatever you want. Here's an example HD rendering at 800x800:
